Improved acceleration
When you switch to Iridium Plugs acceleration is improved.
There is a fast response to throttle operation and you can feel the difference compared to plugs in original plug.

More engine power!
Iridium Plugs improve the engine performance in terms of power.
The extra power becomes apparent in situations like climbing hills, giving you a comfortable driving and touring experience.
